Introducing the Analyzer
The HP 8712ES and HP 8714ES are easy-to-use RF network analyzers
optimized for production measurements of S-parameters. The
instrument integrates an RF synthesized source, S-parameter test set,
multi-mode receivers, and display in one compact box.
The source features 1 Hz resolution, 40 ms (or faster) sweep time, and up
to +13 dBm output power.
S-parameter test sets provide the capability to measure reflection and
transmission characteristics of two-port devices in either the forward or
reverse direction with a single connection. RF power can come out of
either the analyzer’s port 1 or port 2, and either port can be connected to
a receiver. S-parameter test sets also allow full two-port (12 term) error
correction, which is the most accurate form available.
The three-channel, dual mode receivers provide dynamic range of
greater than 100 dB in narrowband measurement mode. For
measurements of frequency-translating devices, the network analyzer
features broadband internal detectors and external detector inputs. The
receivers incorporate digital signal processing and microprocessor
control to speed operation and measurement throughput.
Two independent measurement channels and a large display show the
measured results of one or two receiver channels in several
user-selectable formats. An external VGA monitor can be connected to
the rear panel for enhanced measurement viewing in color.
Measurement functions are selected with front panel hardkey and
softkey menus. Measurements can be printed or plotted directly with a
compatible peripheral. Instrument states can be saved to the internal
floppy disk, internal non-volatile memory, or internal volatile memory.
Built-in service diagnostics are available to simplify troubleshooting
procedures
Measurement calibrations and data averaging provide performance
improvement and flexibility. Measurement calibrations consist of
normalizing data, utilizing the internal factory calibration, or calibrating
with external standards. Measurement calibration reduces errors

associated with crosstalk, directivity, source and load match, and
frequency response. Refer to Chapter 9, “Specifications,” for error
correction specifications.
How to Use This Guide

Installing the Analyzer
Step 1. Check the Shipment
Step 1. Check the Shipment
After you have unpacked your instrument, it is recommended that you
keep the packaging materials so they may be used if your instrument
should need to be returned for maintenance or repair.
NOTE The packaging material is designed to protect the analyzer from damage
that can happen during shipping. Returning the analyzer in anything
other than the original packaging may result in non-warranted damage.
Check the items received against the Product Checklist (included in your
shipment) to make sure that you received everything.
Inspect the analyzer and all accessories for any signs of damage that
may have occurred during shipment. If your analyzer or any accessories
appear to be damaged or missing, call your nearest Hewlett-Packard
sales or service office. Refer to Table 9-10, “Hewlett-Packard Sales and
Service Offices,” in Chapter 9 for the nearest office.

Step 2. Meet Electrical and Environmental Requirements
WARNING If this instrument is to be energized via an external
autotransformer for voltage reduction, make sure that its
common terminal is connected to a neutral (earthed pole) of the
power supply.
5. Install the analyzer so that the detachable power cord is readily
identifiable and is easily reached by the operator. The detachable
power cord is the instrument disconnecting device. It disconnects the
mains circuits from the mains supply before other parts of the
instrument. The front panel switch is only a standby switch and not a
LINE switch. Alternatively, an externally installed switch or circuit
breaker (which is readily identifiable and is easily reached by the
operator) may be used as a disconnecting device.
6. Install the analyzer according to the enclosure protection provided.
This instrument does not protect against the ingress of water. It does
protect against finger access to hazardous parts within the enclosure.
7. Ensure there are at least two inches of clearance around the sides
and back of either the stand-alone analyzer or the system cabinet.

Step 3. Check the Analyzer Operation
1. Turn on the line switch of the analyzer. After approximately 30
seconds, a display box should appear on the screen with the following
information:
• the model number of your analyzer (either HP 8712ES or
HP 8714ES)
• the firmware revision
• the serial number of your analyzer
• installed options
2. Verify that the serial number and options displayed on the screen
match the information on the rear panel serial label.
3. The operator's check should be performed on the analyzer to provide a
high degree of confidence that the analyzer is working properly. Refer
to Chapter 2, “Getting Started,” for instructions on how to perform
the operator's check.

• The VIDEO OUT COLOR VGA port allows you to connect a color
VGA monitor for enhanced viewing. See “Using an External VGA
Monitor” in Chapter 4 for more information.
• The LAN ETHERTWIST connector is for connecting your analyzer to
a LAN (local area network) for control and access. See The LAN
Interface User’s Guide Supplement for information on how to use your
analyzer in a LAN.
HP-IB
Connections
An HP-IB system may be connected in any configuration as long as the
following rules are observed:
• The total number of devices is less than or equal to 15.
• The total length of all the cables used is less than or equal to 2 meters
times the number of devices connected together up to an absolute
maximum of 20 meters. For example, the maximum cable length is 4
meters if only 2 devices are involved. The length between adjacent
devices is not critical as long as the overall restriction is met.
See Figure 1-5 for different connection configurations.

To Set HP-IB
Addresses
Parallel and serial devices often require specific cables—check their
manuals for details. Parallel cable length should not exceed 25 feet. The
analyzer may experience problems talking to a printer if this length is
exceeded. Connect the required control cables and secure them. (Tighten
the knurled screws or comparable fasteners.)
external detectors, connect them to the appropriate rear panel
connectors. See Figure 1-4, “Analyzer Rear Panel Line Module and
Selected Connectors.” Also see Chapter 7, “Front/Rear Panel,” for more
information on front and rear panel connectors.
To communicate via HP-IB, each external device must have a unique
address and the network analyzer must recognize each address. T o check
or set each external device's actual address, refer to the device's manual
(most addresses are set with switches).
The following are examples of how to check or set the device's recognized
address on the network analyzer:
